Like others I have read about on the forum, I get nothing but a white screen. I have tried several different init codes I have found with no luck. I know the signals are getting to the display - I hooked an led to each line with a 1k resistor, so I can see the led change, but not drop the volatge on the line. I am set up for 16bit writes.Kind regards,DavidThe wiring of the unit is1-gnd 11-D/C select 21-D7 31-gnd2-nc 12- nWR 22-D8 32-nc3-nc 13-3.3v 23-D9 33-gnd4-nc 14-D0 24-D10 34-gnd5-nc 15-D1 25-D11 35-gnd6-nc 16-D2 26-D12 36-gnd7-3.3v 17-D3 27-D13 37-gnd8-3.3v 18-D4 28-D14 38-3.3v9-nc 19-D5 29-D15 39-gnd10-gnd 20-D6 30-nRESET

I am trying use the NHD-7.0-800480EF-20 Controller Board with one of your 800x480 resistive displays. I have not been able to find any info on what voltage you feed Pin3 B/L Enable Power Supply Backlight Enable. I am currently doing 3.3v and not having much success - but did not want to try anything higher before asking/Kind regards,David

I realize I can use the 20 pin flex cable and that the connector on the NHD controller is 22 pin - my question is what NHD connector do I need on my custom board to interface to the 20 pin cable?Thanks,David

OK - I have run into another problem with the board. I am running the controller board from a custom interface board. The connector on my custom board is a 20 pin bottom contact 1mm pitch yet the controller board has a 22 pin top contact 1mm pitch connector. The cable is a 20 pin 1mm pitch. So what connector do you sell do I need to purchase to interface my custom board to the controller board?Kind regards,David

I recently purchased NHD-7.0-800480EF-20 Controller Board to go with a 480x800 touch panel from NHD. A couple of questions about the board that I did not see in the docs:1. What voltage does the back light require?2 . Is there a separate ground for the back light? Using a low-side driver to control the brightness is much easier than using a high-side driver.3. How does one use the Display On Signal? Is it as simple as 3.3v turns on the display and 0v turns it off?Kind regards,david

I have a couple of the 800x489 TFT displays. The older one came with the SSD1963 controller and the newer one (NHD-7.0-800480EF-ATXL#-T) without a controller. question 1 - do I need a controller for the newer unit, or can i drive it from the 40 pin cable?question 2 - can I replace the SSD1963 controller board with a NHD-7.0-800480EF-34 Controller Board?question 3 - why did NHD quit using the SSD1963 on the 7" TFT Displays?Thanks and Kind regards,David

The SED1963 data sheet you set the "conf" line to define if the SED1963 is in the 8080 or 6800 mode. In that the NHD‐7.0‐800480WF‐CTXI#‐T does not have the "conf" line, how do you tell the SED1963 which mode to use?Kind regards,David
